WAFER TYPE SOLAR CELL AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to a method for manufacturing a wafer type solar cell and the wafer type solar cell manufactured by the manufacturing method which can solve a contact defect problem between a concave end area of a second semiconductor layer and a reflection preventing layer. The method for manufacturing the wafer type solar cell comprises the following processes: forming an uneven structure on an upper surface of a wafer by etching the upper surface of the wafer and using first reaction gas; and removing a self-mask remaining on the upper surface of the wafer by using second reaction gas. The self-mask is composed of at least one material forming the first reaction gas.
